VfiNTILATING SYSTEM FOR VEHICLES. I

Application filed July 26, 1923. Serial No. 654,041.

To all whom it may concern: Figure 2 is a perspective view. Be it known that WALTER N. METOALF, I Figure 3 is a fragmentary front elevation a citizen of the United States, residing at of the transverse pipe. Evening Shade, in the county of Sharp and Figure 4 is a vertical section taken on 5 State of Arkansas, has invented certain new line H of Fig. 3, showing the manner in and useful Improvements in Ventilating which the sliding plate is associated there- Systems for Vehicles, of which the follow with, the sliding plate being out of engagei i ifi ti n, ment with the apertures in the transverse This invention relates to a ventilating pipe.

The transversely extending pipe 6 In the accompanying drawings forming. is so arranged as to extend longitudinally a part of this specification and in which like at the top of the back ofthe seat 7 in the numerals designate like parts throughout Vehicle as more clearly. shown in Fig. 1 of the same the drawings and this transverse extending Figure 1 is a top plan view showing the pipe 6 is provided with a series of spaced manner and relation in which my ventilatapertures 8. These apertures 8 are so aring system is mounted upon an automobile. ranged in the transverse pipe 6 as to be in This plate 9 is adapted to extend longitudinally within the transverse pipe6 and fits snugly against the inner walls of the pipe 7 for the purpose of cooperating with the apertures 8 formed therein.

A number of slots 10 are provided in the transversepipe 6 and are arranged transversely in the apertures 8 formed therein and are preferably of the bayonet type. The bayonet slots 10 are furthermore provided in the transverse p1pe 6 at the central portion thereof. The sliding plate 9 is provided with a pair of operatinghandles 11 which are adapted to extend through the bayonet.

slots 10 formed in the transverse pipe 6 and are furthermore adapted to operate in the bayonet slots so as to move the plate 9 transversely in the transverse pipe 6 for the purpose of holding the plate 9 in a closed position over the apertures 8 formed in the pipe or upon movement of the handles 11 to the top of the bayonet slots 10 the plate 9 will be brought out of engagement with the apertures 8 and will be furthermore prevented from accidentally covering the apertures when it is desired to allow the fresh air to circulate throughv the pipe 1 to enter the transverse pipe 6 and escape through the apertures 8 formed therein.

- In warm weather it is customary and usually the experience of the driver of the auto mobile to become uncomfortable and warm while driving the same due to the fact that the person operating the vehicle is so seated upon the seat of the vehicle that he cannot very easily move about and thereby is caused 7 to stay in one position all of the time that he is driving. This makes it very uncomfortable for the driver and furthermore there is no means provided whereby a sufficient circulation of air will be received by the driver at the back of the seat to aid in providing comfort to him.

With a ventilating system of the above mentioned character, it can be .well appreciated how the circulation of air will be caused to enter the enlarged inlet opening 3 and pass through the horizontally air circulating pipe 1 into the transverse pipe 6 when the air is permitted to escape through the apertures 8 so as to permit the circulation of air at the back of the seat 2 and around the back of the person operating the vehicle thereby permitting a thorough circulation of fresh air whereby the operator receives the benefits therefrom.

When operating a motor vehicle in coldweather it is not desired to permit cool air passing through the pipe to enter the back of the seat and for the purpose of'preventing the admittance of cool air to the back of the person operatingthe vehicle, I have provided a sliding plate in the transverse pipe 6 which will close all of the apertures 8 when the same is lowered and thereby pre vent the admittance of cool air to the back of the seat and to the interior of the car.

In Fig. 6 ofthe drawings I have shown a modification wherein my ventilating system is adapted to be associated with a motor vehicle which is provided with front and rear seats and the air is obtained through the medium of the cooling fan at the front-of the car. In the construction as shown in Fig. 6, of the drawings, the air enters the enlarged inlet 3 and this enlarged inlet 3 is preferably positioned directly behind the cooling fan 12 so that while the motor vehicle is in operation, the fan will cause a certain amount of air to be directed backwardly and into the enlarged inlet 3 and there the air passes through the horizontally extending pipe 13 which is preferably positioned beneath the floor of the car and this pipe 13 extends longitudinally of the car and has the vertical pipes 14 and 15 respectively in communication therewith. I

Thevertical pipe 14 is adapted to extend upwardly from the horizontal pipe 13 so as to direct the cool air to the back of the front seat while the vertically extending pipe 15 is preferably in communication with the rear end of the horizontally extending air circulating pipe 13 so as to permit a quantity of cool air to enter the back seat of the vehicle. As the construction of the circulating pipes at the seat are the same as heretofore described, it is not thought necessary to further go in detail as to the same, it being sufiicient to state that each pipe 14 and 15 is connected to the transversely extending pipe which permits the air to escape at the rear of the seat is so located as to not interfere with the seating of the occupants in the vehicle.

With a ventilating system of the above mentioned character, the simplicity of the same renders it very efficient in its operation and furthermore does not necessitate the employment of a number ofparts or the alteration of the vehicle in any form. Furthermore' various kinds of vehicles may be supplied with a simple ventilating system of the above mentioned character, and the advantages of the same will be greatly appreciated and will furthermore add to the comfort of the occupants of the car especially during the warm weather.

From the foregoing description of the construction of my improved apparatus, it will be seen thatI have provided a simple, inexpensive and efficient means for carryingout the objects of the nvention, and while I have particularly d cribed the elements best iii outwardly from the body of tending horizontally in the body of said vehicle, the inlet of said air pipe extending screen for the said inlet end of said circulatsaid vehicle, a

ing pipe, a transverse pipe associatedwith 15 the opposite end of said air circulating pipe, said transverse pipe extending longitudinally at the back of said seat, said transverse pipe provided with a series of apertures for the purpose of admitting cool air at the back 20 of said seat, and a plate slidably mounted in said transverse pipe and adapted to cover I said apertures, said slidable plate adapted to move longitudinally and vertically guided by slots formed in said transverse pipe ad- 25 jacent said apertures.

In testimony whereof I aflix my signature.
